Experimenting with Macrotechniques

I have been experimenting trying to find out how many images I need to stack to produce front-to-back sharpness in my small insect images with around f5.6. I concluded that only 7 of the series of 15 images I traditionally use contain any elements that are in focus for my very small subjects so I have been stacking just those frames and get much cleaner images without haloing. I have now set the stack number to 10 though will still only stack those frames with something in focus. With single shots, I tried high aperture number eg f18 or F22 (last 4 images) but the quality certainly falls off when fully closed down (last image). Lucky to have some great models for my experiments particularly the Tachina fera mating pair mating comfortably in a folded leaf and the Dung Fly exuding a droplet of water which is reflecting the spurge flowers it is resting on.

Meet Misumena our Macrophotography Model

Yesterday the RPS and CCC Nature Groups held a very informative Macro workshop led by David Smith of OM-Systems. Although he had his own model, Frankie, the Ghost Mantis, I think Misumena 1 and Misumena 2, a couple of flower spiders, stole the show. This is M2 parading rather attractive dark green patches and stripes - excellent for hiding in Meadow Sweet flowers.  They can change colour (not sure of the timescale of the changes) and often those in Buttercups are bright yellow. 

These are mainly single shots at F13-F18 but the last two are an in-camera jpeg stack versus a stack done from Raws in Zerene stacker.

Overcast but very warm day produced lots of insect activity including this beautiful male Orange Tip Butterfly and this very hairy Anthomyoiid Fly feeding on a dead Snail. Otherwise spiders in abiundance and 10 species of Plant Bug (Dock and Hairy Bug not shown)..

Paxton Survey - Sanctuary

I did a survey of the sanctuary and the Meadow along side it on Thursday as I could't go on Saturday.Here are some of the more confiding insect and spider species - over 50 more or less identified.

Insects from Royston Heath

Here a few images from our afternoon visit to Royston Heath on Friday in a sheltered spot where there were flowering Berberis bushes and Alexander plants plus lots of nettles supporting many different species. I was pleased with the accidental capture of a beetle taking off, mating Bibio flies, Nursery spider with Crane Fly, Brown-tailed Moth caterpillars which will strip all the hawthorn bushes etc, Andrena fulva, Lygos Bug, two species of Click Beetles, Ichneumon wasp, Hawthorn Bug, Common Carder bee and Ashy Mining Bee
